The 3-hole blade from SOTA is made of natural-colored tungsten carbide and is supplied uncoated. It has been developed for precision cutting of foil and separators in lithium battery industrial applications. For this specialized application, the cutting edge quality of the blades is subject to exceptionally strict controls. Each blade is inspected under magnification, with chip depths limited to less than 0.01 mm. This ensures high-quality blades that deliver consistently precise cutting performance and contribute to the safe processing of lithium batteries.
